The control section 10 contains a CPU, a ROM and the like. The control section 10 has a function to execute a game program read out by the game program reading section 30 and stored in the storage section 20 and to carry out various kinds of controls for causing a video game to proceed in response to an operation of a player. In the present embodiment, the control section 10 includes a music reproducing section 11, a point value updating section 12, a determining section 13, an updating section 14, and a mode shifting section 15.

The music reproducing section 11 has a function to select music according to scenario progress of the video game in accordance with the game program and to reproduce the music. As the music to be reproduced, music indicated by music information stored in a music information storage section 22 is selected.

The point value updating section 12 has a function to carry out a process to update a game point value in accordance with a progress status of the video game. Namely, the game point value is added and updated when a player character applies a damage to an enemy character or when the player character receives a damage from the enemy character. The game point value is configured to be increased and reduced between 0 and 100 in accordance with progress of the video game. In this regard, the point value updating section 12 may be configured so as to subtract and update the game point value when a distance between the player character and the enemy character becomes a constant value or more or when the player character uses, for itself, an in-game item that causes the game point value to be lowered.

The determining section 13 has a function to carry out various kinds of determining processing, such as determining processing whether a reproducing style of reproduced music is to be updated or not (music reproducing style update determining processing), determining processing whether an appearance style of the player character is to be updated or not (appearance style update determining processing), and determining processing whether it can be shifted to a special mode or not (special mode shifting possibility determining processing). More specifically, in the music reproducing style update determining processing, the determining section 13 refers to the updated game point value and music reproducing style information to determines whether the reproducing style of the reproduced music is to be updated or not. In the appearance style update determining processing, the determining section 13 refers to the updated game point value and appearance style information to determine whether the appearance style of the player character is to be updated or not. In special mode shifting possibility determining processing, the determining section 13 refers to the updated game point value to determine whether the video game can be shifted to a special mode or not. In this regard, the special mode will be described later in detail.

The updating section 14 has a function to carry out processing to update a reproducing style of the reproduced music (music reproducing style updating processing) and processing to update an appearance of the player character (appearance style updating processing). In the music reproducing style updating processing, the updating section 14 updates the reproducing style of the reproduced music to a reproducing style according to the updated game point value. Further, in the music reproducing style updating processing, the updating section 14 updates, during the special mode, the reproducing style of the reproduced music to a reproducing style dedicated to the special mode. In the appearance style updating processing, the updating section 14 updates the appearance style of the player character to an appearance style according to the game point value. Further, in the appearance style updating processing, the updating section 14 changes, during the special mode, the appearance style of the player character into an appearance style dedicated to the special mode.

The mode shifting section 15 has a function to carry out a process to shift to the special mode in a case where it is determined that the video game can be shifted to the special mode by the determining section 13.

Here, the “special mode” is a mode to which the video game can be shifted when the game point value becomes a predetermined value. In a case where a predetermined shift request operation is received from a user when the game point value becomes the predetermined value, the mode is shifted to the special mode. The special mode according to the present embodiment is a mode in which a status of the player character is increased dramatically. During the special mode, processings dedicated to the special mode are carried out in various kinds of controls regarding to the progress of the video game, such as a BGM control (for example, the music reproducing style updating processing) and a character appearance style control (for example, the appearance style updating processing). In this regard, the video game may be configured so that, when the game point value becomes the predetermined value, a mode shifting is carried out without receiving a shift request operation from the user.

The music reproducing style information according to the present embodiment contains tracks each of which is updated in the reproducing style from the silent state (“Volume0” in the present embodiment) to the sound state (“Volume1 to Volume5” in the present embodiment). Further, a magnitude correlation of the volumes is configured so that the volume becomes larger as the reproducing style becomes closer to “Volume5”. Further, the “tempo” according to the present embodiment is configured so that all of the tempos of the respective tracks contained in the one piece of music are the same as each other even though the reproducing style is any reproducing style. Namely, the tempos of the respective tracks when the reproducing style for “music A” is “level2” are stored as “

=65” for all of “vocal”, “guitar”, “base”, and “drum”.

Further, the “level” in the music reproducing style information according to the present embodiment is used to classify the reproducing styles into multiple stages, and corresponds to the game point value. The “level” is configured so that a level1 corresponds to a game point value “zero or more and under 10” (0≦point value (p)<10), a level2 corresponds to a game point value “10 or more and under 20” (10≦point value (p)<20), . . . , and a level10 corresponds to a game point value “90 or more and 100 or less (90≦point value (p)≦100). Namely, the “level” in the music reproducing style information according to the present embodiment is configured so as to shift to next level whenever 10 of the game point value is accumulated. In other words, the video game processing apparatus 100 is configured so as to update the reproducing style of the music whenever 10 of the game point value is accumulated. In this regard, the music reproducing style information is not limited to a configuration in which “levels” divided into 10 stages like the present embodiment is used.

In the present embodiment, the audio reproducing section 60 reproduce the sound data of each track stored in the music information and sound for an action of the player character.

The player operation receiving section 70 receives an operational signal in response to an operation of the player, and notifies the control section 10 of the result.

The communication section 80 connects the video game processing apparatus 100 to a communication network such as the Internet by means of a wireless or wired manner to transmit and receive various kinds of information.

Next, an operation of the video game processing apparatus 100 according to the present embodiment will be described. In this regard, the content of an operation and/or processing with no relationship to the present invention may be omitted.

FIG. 6 is a flowchart showing an example of battle processing in the video game processing apparatus 100. The battle processing is started when requirements for start of a battle between the player character operated by the user and the enemy character operated by the control section 10 are satisfied in accordance with the progress of the video game.

In the battle processing, the control section 10 first starts to reproduce music indicated by music information using a reproducing style according to a game point value (Step S101). Namely, the control section 10 selects music to be reproduced from the music information; refers to the music reproducing style information and the game point value to determine a reproducing style of the selected music; and reproduces the music on the basis of the determined reproducing style. In this regard, the control section 10 according to the present embodiment starts reproducing a plurality of tracks constituting one piece of music at the same time by matching start positions of the plurality of tracks. Namely, the control section 10 reproduces the one piece of music as the BGM by reproducing the plurality of tracks so as to be superimposed.

Here, reproduction starting processing for music according to the present embodiment will be described specifically. Here, a case where music to be reproduced is the music A and a battle is started in a state that the game point value is zero will be described specifically as an example. As shown in FIG. 2, the music A is first constructed by four tracks of “vocal”, “guitar”, “base” and “drum”. As shown in FIG. 3, a level corresponding to the game point value “0” in the music reproducing style information is “level1”. Therefore, a track for “vocal” is reproduced at “Volume1/

=60”, a track for “guitar” is reproduced at “Volume0/

=60”, a track for “base” is reproduced at “Volume0/

=60”, and a track for “drum” is reproduced at “Volume1/

=60”. Namely, in a case where music to be reproduced is music A and a battle is started in a state that the game point value is zero, all of the tracks are reproduced in the inside of the video game processing apparatus 100, but the video game processing apparatus 100 carries out reproducing processing for the music so that the user is allowed to listen only sounds of the “vocal” and the “drum”.

Further, the video game processing apparatus 100 may be configured so as to refer to the appearance style information and the game point value when to reproduce the music, and determine an appearance style of the player character. Namely, the video game processing apparatus 100 can be configured so as to, when to start reproducing the music, determine a reproducing style of the music and determine the appearance style of the player character.

In this regard, when to carry out the reproduction starting processing for the music, the control section 10 selects music indicated by the music information in accordance with a predetermined selection rule. As the predetermined selection rule, a rule to refer to information in which the player character is associated with the music to select music corresponding to the player character, a rule to refer to information in which the enemy character is associated with the music to select the music corresponding to the enemy character, a rule to refer to information in which the game point value is associated with the music to select the music corresponding to the game point value when a battle is started, and the like are used, for example.

When the reproduction of the music is started, the control section 10 updates the game point value in accordance with the progress status of the video game (Step S102). Namely, the control section 10 updates the game point value in response to a situation in which the player character gave a damage to the enemy character or a situation in which the player character received a damage from the enemy character.

On the other hand, when the game point value is updated, the control section 10 determines whether a reproducing style of the reproduced music is to be updated or not (Step S103). Namely, the control section 10 refers to the updated game point value and the music reproducing style information, and determines whether the reproducing style of the reproduced music is to be updated or not. In the present embodiment, the music reproducing style information is information in which the level corresponding to the game point value is set up. For this reason, it is determined whether the updated game point value becomes a game point value corresponding to a level different from the current level or not.

In a case where it is determined that the reproducing style of the reproduced music is not to be updated (“No” at Step S103), the control section 10 does not update the reproducing style, and refers to the appearance style information to determine whether the appearance style is to be updated or not (Step S105).

On the other hand, in a case where it is determined that the reproducing style of the reproduced music is to be updated (“Yes” at Step S103), the control section 10 updates the reproducing style of the music to a reproducing style for a level corresponding to the game point value (Step S104).

Here, the updating processing for the reproducing style of the music according to the present embodiment will be described specifically. In this case, a case where music to be reproduced is music A and the game point value is updated to 10 after a battle is started in a state that the game point value is zero will be described specifically as an example. When the game point value becomes 10, as shown in FIG. 3, the level of the reproducing style is changed from “level1” to “level2”. Therefore, the track for “vocal” is reproduced at “Volume1/

=60”, the track for “guitar” is reproduced at “Volume1/

=60”, the track for “base” is reproduced at “Volume1/

=60”, and the track for “drum” is reproduced at “Volume1/

=60”. For that reason, the video game processing apparatus 100 reproduces the music with the reproducing style, in which the sounds of only “vocal” and “drum” can be heard, when a battle is started in a state that the music to be reproduced is the music A and the game point value is zero. The video game processing apparatus 100 then reproduces the music with the reproducing style, in which the sounds of “guitar” and “base” can also be heard, in a case where the game point value becomes 10. Namely, the user gets the impression that the sounds are added to the previous sounds so as to be synchronized with the previous sounds in accordance with the progress status of the video game. According to such a configuration, even in a case where a rendering that gives the user a feeling add a track is carried out, it becomes possible to carry out an additional rendering of the track without generating a deviation in introducing timing of an additional track in the present embodiment, the track that becomes the sound state from the silent state).

When the reproducing style of the music is updated, the control section 10 refers to the appearance style information to determine whether the appearance style is to be updated or not (Step S105).

In a case where it is determined that the appearance style of the player character is not to be updated (“No” at Step S105), the control section 10 determines whether the appearance style is to be shifted to the special mode without update or not (Step S107). On the other hand, in a case where it is determined that the appearance style of the player character is to be updated (“Yes” at Step S105), the control section 10 refers to the appearance style information to update the appearance style to an appearance style with a level corresponding to the game point value (Step S106). In a case where it is determined that the appearance style is to be updated, the control section 10 determines whether the appearance style is to be shifted to the special mode or not (Step S107).

In a case where it is determined that the appearance style is not to be shifted to the special mode (“No” at Step S107), the control section 10 causes the processing flow to return to Step S102, and carries out the process to update the game point value in accordance with the progress of the video game.

On the other hand, in a case where it is determined that the appearance style is to be shifted to the special mode (“Yes” at Step S107), the control section 10 refers to the special mode music reproducing style information to update the reproducing style of the reproduced music to a reproducing style during the special mode (Step S108), and refers to the special mode appearance style information to update the appearance style of the player character to an appearance style during the special mode (Step S109).

Here, the updating processing for the reproducing style of the music when the video game is shifted to the special mode according to the present embodiment will be described specifically. Here, a case where music to be reproduced is music A and mode shifting becomes possible when the game point value is 90 or more will be described specifically as an example. A level of the music reproducing style when the game point value is 90 is 10, as shown in FIG. 3. When the level of the music reproducing style becomes 10, as shown in FIG. 3, the track for the “vocal” is reproduced at “Volume3/

=100”, the track for the “guitar” is reproduced at “Volume3/

=100”, the track for the “base” is reproduced at “Volume3/

=100”, and the track for the “drum” is reproduced at “Volume3/

=100”. When a mode shifting request operation is received from the user in such a reproducing style, the control section 10 carries out mode shifting processing to shift the mode of the player character to the special mode. When to shift to the special mode, as shown in FIG. 5, the track for the “vocal” is reproduced at “Volume5/

=130”, the track for the “guitar” is reproduced at “Volume4/

=130”, the track for the “base” is reproduced at “Volume4/

=130”, and the track for the “drum” is reproduced at “Volume4/

=130”. Therefore, the video game processing apparatus 100 can reproduce the music with the reproducing style using the volume and the tempo of the music different from those in a normal mode so as to be matched with a portion to be livened up further in the video game without taking any account of a sound break and the like when the reproducing styles are changed.

When the music reproducing style and the appearance style are respectively updated to the music reproducing style and appearance style during the special mode, the control section 10 determines whether the special mode is to be terminated or not (Step S110). In a case where it is determined that the special mode is not to be terminated (“No” at Step S110), the control section 10 determines whether the special mode is to be terminated or not again. Namely, the control section 10 repeats the process at Step S110 until it is determined that the special mode is to be terminated.

On the other hand, in a case where it is determined that the special mode is to be terminated (“Yes” at Step S110), the control section 10 terminates the special mode, resets the game point value (Step S111), and causes the processing flow to shift to the process at Step S102 to update the game point value in accordance with the progress status of the video game.

As explained above, in the embodiment described above, the video game processing apparatus 100 for controlling progress of a video game is configured so as to include: the music information storage section 22 configured to store music information indicating music, the music being constructed by a plurality of tracks, the music being reproduced with plural kinds of reproducing styles by reproducing an arbitrary combination of one or two or more tracks; and the music reproducing style information storage section 23 configured to store music reproducing style information, the music reproducing style information indicating a reproducing style of music according to a game point value, the game point value denoting a value of a game point that changes in accordance with the progress status of the video game, and so as to: start reproduction with a reproducing style according to the game point value and reproduce the music indicated by the music information (for example, Step S101); update the game point value in accordance with the progress status of the video game (for example, Step S102); refer to the updated game point value and the music reproducing style information to determine whether the reproducing style of the reproduced music is to be updated or not (for example, Step S103); and update the reproducing style of the reproduced music to a reproducing style according to the updated game point value in a case where it is determined that the reproducing style is to be updated (for example, Step S104). Therefore, the video game processing apparatus 100 is configured so that the reproducing style of the reproduced music is updated in accordance with the progress status of the video game, such as a situation that the player character gives the enemy character a damage.
